Hans Oerlemans

Hans Oerlemans is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hans Oerlemans rather than just read about it. In short: Johannes "Hans" Oerlemans (born October 8, 1950 in Eethen) is a Dutch climatologist specialized in glaciology and sea level. He has been a professor of meteorology in the Faculty of Physics and Astronomy at Utrecht University since 1989.

Key takeaways

Hans Oerlemans belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Hans Oerlemans to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hans Oerlemans from memory before moving on to harder problems.

Reference excerpt

Johannes "Hans" Oerlemans (born October 8, 1950 in Eethen) is a Dutch climatologist specialized in glaciology and sea level. He has been a professor of meteorology in the Faculty of Physics and Astronomy at Utrecht University since 1989. He was elected a member of the Royal Netherlands Academy of Arts and Sciences in 1994. In 2001 he won the Spinoza Prize. In 2010 he was made a Knight of the Order of the Netherlands Lion. In 2022 he was awarded the Balzan Prize for Glaciation and Ice Sheet Dynamics together with Dorthe Dahl-Jensen.

Worked examples

Example 1 — a first encounter with Hans Oerlemans

Start with the simplest possible case. Write down what Hans Oerlemans claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hans Oerlemans before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hans Oerlemans ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hans Oerlemans

In research: Hans Oerlemans appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hans Oerlemans in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hans Oerlemans is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 births, Academic staff of Utrecht University, Dutch climatologists, so understanding it makes those chapters shorter.
In everyday life: Look for Hans Oerlemans outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
